I have collected the amount of times a champion appears in my games over the past 18 games. Out of 143 champions, 101 were polled. 42 champions were missing from the poll. Here is the probability of them being in my games. Where possible, I reduced fractions.
Statistically speaking (I am terrible correct me if I am wrong), counting by times the champions; Malphite, Vlad, Velkoz, Kayle, and Veigar are the most rolled champions in my past games. The champions with highest probability are Malphite and Vlad.
If anywhere my math is incorrect, feel free to correct me. Let me know the champ you see the most!
